The clean out at the top of securities market operator NZX continues with the departure of Head of Corporate Office, Rowan Macrae.

Widely see as former NZX boss Mark Weldon’s right-hand woman towatds the end of his tenure, Macrae left NZX on October 31 to pursue other opportunities according to a release this morning. She had been with the company for eight years.

As is often the case with a new CEO, several members of the NZX leadership team have resigned since Tim Bennett took over from Mark Weldon.

Last month, NZX tapped Mandy Simpson as its new head of operations, marking the firm's third high level reshuffle in under a month. She replaced Simon Smith who had spent eight years with the firm across a number of roles.

That appointment came just weeks after NZX named former Minster of Commerce Simon Power and 2015 Cricket World Cup head Therese Walsh to its board, and saw Sky City Entertainment chairman Chris Moller depart. It also named director James Miller to the newly created position of deputy chairman.

Ten days before those appointments, NZX hired Bevan Miller as its chief financial officer role, a role created by Bennett. Miller had previously served in same capacity at private hospital operator Acurity Health.
